2020 expy/Navi changes?

The noise you hear is the pumped in noise from the speakers. If you have forscan, you can turn it off and make the ambiance a bit quieter.

The speakers make a reasonable rumble when you get on it, the tailpipe makes the v6 whaling sound that I hear constantly.
I'm picky, most probably don't notice it....

I was also scared of the 6 cylinder...all our vehicles are V8 and off road stuff big engines too. I really like the power of the '16 Expy better than the '04 & '06. As for the speaker engine sound mine does not have that.

Actually the tuner made my exhaust sound a little better. Borla is a few weeks from the release of an exhaust for the expidition. They currently make one for the navigator. See the you tube of the Hennessy navigator. Sounds pretty good.
